Whoever at Apple mentioned this is incorrect. File sharing is definitely quite possible between all versions of OS X. Try connecting the two systems directly using an Ethernet cable to see if by using a self-assigned IP address scheme the systems can communicate properly and show up in each others' Finders.

Hello Topher. I was pretty sure I was being given incorrect information. I tried to get clarity, but it was clear that all three of the support staff were either apathetic, or simply did not have the knowledge needed to answer the question. It is dangerous to answer incorrectly, and I have had a pooor experience of Apple Support in the past also.
Moving on though, They are on different floors, so ethernet is not practical. We use WiFi locally. One of the machines was upgraded to Lion (the worst most and most incomplete OS I have ever experienced, but I digress…). It used to connect on this network, but now it does not.
So, a 10.7 CAN connect to a 10.6 as I would have expected, this is progress. Why do they not show up in Network?

To their credit they may have mistaken some details and might have been thinking about Windows file sharing, which was changed from an open-source package to an Apple-provided package in Lion, and resulted in some compatibility issues when using it, but Apple's file sharing is quite compatible across all versions.
I'd be curious to know if you are certain both systems are on the same wi-fi network. Additionally, do other systems see each other just fine? Can you ping each system (open the Terminal on one and type the command "ping IP", substituting IP for that of the system being targeted)? I'm also assuming you have File Sharing turned on for both, but in addition you can try turning on other sharing services such as Remote Desktop and Remote Access to see if you can otherwise access the system through screen sharing or thorugh SSH in the Terminal.
